Pall (PLL-3.1%) is the S&P's top loser after J.P. Morgan cuts shares to Underweight following a weak FQ2 report. PLL made it clear in its conference call that its rate of volume growth for 2012 is slowing, the firm says; FQ2 sales measured in local currency rose 8%, but orders rose 3.4%. PLL thus has a "reasonable probability" of missing estimates in coming quarters.
